Microburst last for a few seconds and are inconsistent with surrounding wind speeds. They also go top to bottom rather than side to side like wind. That’s why they’re dangerous, they push planes down. I believe mt Washingtons was fastest sustained/recorded winds in the US. New record is Australia at 253mph. As a former pilot, they are scary as fuck. Thank god we have new warning systems. But they only buy you a minute or two of warning.

That caused me pause too. Perhaps the article was referring to a stereotypical anemometer with spinning cups, versus Mt Wash’s hot wire anemometer.
